忘掉廉价的肥肉、甘蔗或菜籽油吧,西瓜有望在未来成为生物燃料的来源。科学家们发现,水果中含有大量糖分,可直接用于提炼酒精,从而为汽车和农用机械提供动力。每年仅美国的零售商遗弃的“不合格”水果就达36 万吨,而这些水果可通过一种十分经济的方法来制造燃料。 Forget the cheap fat, sugar cane or rapeseed oil, watermelon is expected to become a source of biofuels in the future. Scientists have found that fruits contain large amounts of sugar that can be directly used to extract alcohol to power automobiles and farm machinery. Only 360,000 tons of “unqualified” fruit are discarded each year by U.S. retailers, which can produce fuel in a very economical way.
